Tavis Ormandy and Will Drewry, both of the Google Security Team,
discovered that the SSL_get_shared_ciphers() function contains a buffer
overflow vulnerability, and that the SSLv2 client code contains a flaw
leading to a crash. Additionally Dr. Stephen N. Henson found that the
ASN.1 handler contains two Denial of Service vulnerabilities: while
parsing an invalid ASN.1 structure and while handling certain types of
public key.

Impact
======

An attacker could trigger the buffer overflow vulnerability by sending
a malicious suite of ciphers to an application using the vulnerable
function, and thus execute arbitrary code with the rights of the user
running the application. An attacker could also consume CPU and/or
memory by exploiting the Denial of Service vulnerabilities. Finally a
malicious server could crash a SSLv2 client through the SSLv2
vulnerability.
